Definitions

  • the present invention refers to a valve for purging air in the filling and admission thereof during the emptying of pressurized liquid flow ducts, which has a float system and a membrane connected to each other in order to permit the removal of air accumulated and/or produced in pressurized liquid flow ducts, permitting in the case of a reduction of pressure the intake of air, so that adequate performance of certain ducting parts, such as filters, etc., is achieved.
  • the purpose of the invention is to provide the corresponding sector in particular and the public in general, with a valve of the above-cited type, but with some particular characteristics from which greater structural simplicity of the valve, more efficient operation, and, in turn, some better performance qualities with respect to other valves having the same function are derived.
  • valves that are assembled in pressurized water or liquid flow ducts are known. Their purpose is to eliminate small amounts of air that are accumulated or produced in the ducts themselves. In some cases, these valves are made in such a way that they also permit the outflow of large amounts of air.
  • valve described in said European patent is designed to remove small amounts of air as well as large amounts of air that is normally carried out by independent valves, called “automatic valve” in the first case and “kinetic valve” in the second case.
  • valve object of the invention has some basic characteristics like the ones cited in the preceding section, but with a series of innovations from which structural and functional advantages with respect to the type of valves described in the European patents alluded to before are derived.
  • the valve in question is comprised, since it is a conventional valve, of a hollow body defined by the coupling by means of threading of two parts, one of which is provided with a coupling for the fluid intake.
  • a float Inside the hollow body, there is a float connected to a flexible membrane which in a normal position presses, by thrust of the fluid on the float, against a valve seat, closing the air outlet, whereas when air is produced the float moves in the opposite direction by the effect of the difference of density, separating the membrane from the whole or from the seat thereof, allowing the outflow of air.
  • a first novel characteristic of the valve of the invention is centered on the fact that the air outlet is a single grooved-form hole, through which air comes out in small amounts or the air comes out in large amounts, with the particularity that this outlet extends outside on a neck with an inside thread in order to permit the coupling of other outside devices, for example, for the ducting of possible leaks of liquid during normal operation of the valve.
  • the membrane should be assembled obliquely, specifically on a chamfered surface of the float, a surface, which is defined as a side top surface.
  • protrusions and projections define a means for optimum positioning of the membrane, as well as efficient operation thereof.
  • the cited flexible membrane has one of its edges cylindrically thickened for tight coupling and by sliding in the top channel (as one can see in the attached drawings) established for this purpose in the top end area of the side top part of the float, all in such a way that the valve fastened by the top end will carry out the function of removing air when the duct is pressurized or will allow the intake of air when the duct is depressurized in order to prevent the collapsing of the parts. In this way, it carries out a function of protecting the installation.
  • valve lies on the shape of the float, which is formed by an elongated body with an aerodynamic design.
  • the body of the valve occupies a large part of the hollow.
  • the cited float has some guiding means for the coupling or correct assembly thereof inside the valve body.
  • the guiding means are comprised of (male) protrusions complementary of the (female) channels provided for this purpose on the inside side surface of the part of the valve body, which prevents the float from being incorrectly put in place.
  • valve of the invention is formed by the coupling between two parts (1) and (2), defining a hollow body inside of which a float (3) is assembled.
  • a flexible membrane (4) is assembled on the float, in such a way that the part (2) has a threaded extension (5) defining a coupling means for the intake of fluid into the general body of the valve.
  • a hole (6) is defined, according to an oblique arrangement, for the removal of air.
  • the valve body has an outside extension defining a neck (7) with an inside thread in order to couple devices, for example, for collecting water that might be expelled with the air, etc.
  • the float (3) has side protrusions (8) that in the assembly thereof inside the valve body are guided in channels (9) established for this purpose on the inside surface of the part (1) corresponding to the valve body.
  • the flexible membrane (4) As to the flexible membrane (4), it has some protrusions (10) and some projections (11) in order to rest on the side top part of the float (3), defining an effective, simple and optimum means for positioning and assembling said flexible membrane (4) on the float (3), just as it is represented in figures 3 and 4. Besides there is the particularity that the cited membrane (4) has in one of its opposite edges a cylindrical thickening (12) used to house, in a complementary cavity (13) formed for this purpose in the corresponding part of the float (3). Hence, the flexible membrane (4) remains perfectly fastened to the float (3).
